I'm not sure what this example shows. Does anyone have an idea of what this bug actually is?

I think the idea is that syntax coloring should be multi-line.
E.g. when starting a quote with the backtick or triple double-quotes, if the string starts on the same line, then the text on the first line is coloured green.
However, the lines after the first are coloured normally (black with blue for keywords, etc) even though they are part of a string.
Finally, if the end of a multiline quote has text before the end quote and text after the end quote (say in a comment perhaps), then the text that's part of the string before the quote is incorrectly coloured normally, but the text that comes after the end of the string is coloured as if it was part of a new string (which it isn't).
Here's something which better demonstrates the problem:
with trace
trace(1)
sequence help_message =
`You will be presented with a sequence of %d digits randomized. You can reverse the first X digits by entering the position number
aaat the play prompt. The goal is to sort the list in the fewest number
of mo`-- test ves.

We seem to have a similar issue with multi-line comments.

Oh! So...is this a library issue, or a trace / interpreter issue?
I hadn't even thought about the interactive trace screen. This sounds like a tokenizing problem. Hmm...we have a syncolor.e in include/euphoria and in source, which makes this more confusing.
I agree that it would be nice to properly color the tracing lines based on multi-line constructs.

It's a library issue. ed.ex has the same issues that the trace screen has.
source/syncolor.e just piggybacks on include/euphoria/syncolor.e - it acts as a bridge between it and be_syncolor.c (and is new to 4.1) (The nice thing about 4.1 is that all the syncolor stuff is unified.)
